- •
Hollow activated carbon microtubes (HACMs) are prepared from willow catkins for the first time.
- •
The HACMs show high surface area of 1107 m2 g−1 and concentrated pore size distribution.
- •
The HACMs electrode exhibits high gravimetric capacitance of 306 F g−1 and outstanding volumetric capacitance of 303 F cm−3.
